Abstract

Grasslands of middle mountain regions are among the most diverse habitats of the Carpathian Basin, but they are threatened by spontaneous succession leading to woody encroachment. It is a high priority of nature conservation to preserve these diverse habitats by suppressing the woody encroachment and to create new open habitat patches by scrub removal. The main goal of this study was to investigate the effect of shrub cover on plant species composition and vegetation in terms of relative ecological indica-tor values in semi-natural grassland patches. We also aimed at studying the wild browsers’ preference for woody species, which potentially plays a role in shrub encroachment. The study was conducted in the Mátra mountains, North-Hungary, where three study sites were selected within the Fagetalia belt: two sites recently restored by scrub removal with different post-restoration management and a semi-natural grassland as a control site. All of the sites were available for wild ungulate grazing. At each study site, vegetation and browsing data were recorded at 50 sampling points for which we used circu-lar plots with a radius of 1.13 m (4 m2). The highest shrub cover was found in the clearing that was grazed only by wild ungulates. The linear regression analysis showed that shrub cover significantly increased the abundance-weighted nutrient (NB) and water (WB) scores and decreased the naturalness value (SBT). Moreover, we found that an increase of shrub cover significantly decreased cover and species richness of grassland specialists, but increased weed cover. Most of the woody species were browsed in relation to their abundance except Rubus and Acer species, which were non-preferred. Our results highlight that shrub encroachment has a negative effect on semi-natural grasslands and that beside wild ungulate browsing additional management is needed to preserve these diverse habitats.

Abstract

Festucetum vaginataeRapaics ex Soó 1929 em. Borhidi 1996 is a characteristic association of the calcareous sandy areas of the Pannonian basin; its dominant grass species is Festuca vaginata. Another typical species of these sandy areas is the newly discovered F. pseudovaginata. The question is whether F. pseudovaginataforms an independent coenotaxa? Our study proved that F. vaginataand F. pseudovaginatapopulations grow separately and compose different associations. Stands dominated by F. pseudovaginatahad a higher species richness and harboured twice as many Festuco-Brometeaspecies compared to the Festucetum vaginataestands. Diagnostic species of the Festucetum pseudovaginataeassociation are Festuca pseudovaginata, Colchicum arenarium, Ephedra distachya, Koeleria majoriflora,and Astragalus onobrychis. The number of species, the density of the individuals, and the variability and diversity of the vegetation separated it from the Festucetum vaginataeassociation; thus, it can be considered an independent endemic association. Festucetum pseudovaginataehas its own differentiating and dominant species: Carex stenophylla, Cynodon dactylon, Eryngium campestre, Kochia laniflora.
